This elaborate custom PC was built for display at this year's QuakeCon. You can take your pick as to what's most amazing about the project: the fact it works, the fact it looks identical to a terminal from Fallout, or the fact the entire thing cost under $60.

The PC's exterior is hand-made, while the screen is an old CRT unit. It's running Ubuntu, and that hacking game you see on the screen isn't static; it's been programmed to actually work as a Fallout hacking game.
